摘要： The invention relates to a release valve (100), installable on a container intended to contain a pressurized fluid and capable of maintaining a pressure difference between a first environment (9) and a second environment (90), comprising a housing (8), a first thrust means (3), a closure element (5), and a slider (2), wherein said housing (8) contains at least said slider (2) and said first thrust means (3), wherein said slider (2) comprises a first surface (25) facing the first environment (9), and a second surface (26), facing the second environment (90), and having an area greater than said first surface (25), wherein said closure element (5) is interposed between said second environment (90) and said slider (2), and wherein said first thrust means (3) is positioned between said slider (2) and said housing (8), so as to obtain at least one closed contact profile between said closure element (5) and said second surface (26), wherein said release valve (100) is characterized in that said fluid exerts on said second surface (26) a pressing force greater than the pressing force exerted on said first surface (25), and in that said first (25) and second (26) surfaces are arranged in such a way that, if the pressure difference between said first environment (9) and said second environment (90) remains below a predetermined value, said first thrust means (3) realizes said closed contact profile between said closure element (5) and said slider (2).

摘要： The present invention relates to a gas spring comprising a first element, a second element, and a limit, wherein the second element comprises a first chamber and a first opening for accessing the first chamber, the first element is fixable to a reference plane and comprises a second chamber), a second opening for accessing the second chamber, and external walls, and is inserted into the first chamber through the first opening, wherein said first and second elements are movable and reciprocally slide along an axis, wherein the limit comprises a stem and a head adapted to slide through the second opening into the second chamber parallel to the axis so as to limit the maximum travel of the second element to the extension of the external walls of the first element, wherein said first and second chambers communicate through an existing play between said stem and said second opening, and the second element slides through the first opening along the external walls of the first element.

摘要： Described is a gas spring (200), comprising a guide (2), having an outer surface (212), a slider (1), defining with said guide (2) at least one chamber (11) containing pressurised gas, said slider (1) being slidably connected to said guide (2) in such a way as to have a maximum stroke, of expansion, wherein said guide (2) is partially extracted from said slider (1), and a maximum stroke, of compression, characterised in that it comprises a bushing (3), positioned between said slider (1) and said guide (2), comprising sealing means for the tightness of the chamber (11), and



removably coupled and so as to move integrally with said slider (1) up to said maximum stroke, in such a way that, when said slider (1) slides with respect to said guide (2) beyond said maximum stroke, said bushing (3) decouples from said slider (1) so as to eliminate the seal of the chamber (11).
